arm64: dts: rockchip: Add frl-enable-gpios to rk3576 boards
The following RK3576 boards expose a GPIO pin to control the voltage
bias on the HDMI data lines:
- rk3576-100ask-dshanpi-a1
- rk3576-armsom-sige5
- rk3576-evb1-v10
- rk3576-evb2-v10
- rk3576-nanopi-m5
- rk3576-roc-pc
- rk3576-rock-4d
The pin must be asserted when operating in HDMI 2.1 FRL mode and
deasserted for HDMI 1.4/2.0 TMDS mode.
Wire up the hdmi node to its dedicated GPIO via frl-enable-gpios to
allow adjusting the bias when transitioning between TMDS and FRL modes.
